COVID-19 Vaccine
COVID-19 vaccines lower the risk of getting sick and, most importantly, of severe illness, hospitalization, and death.
Like the flu shot, the vaccine is updated to match the strains circulating, so staying up to date is what keeps protection strong.
The Basics
COVID-19 can range from mild to severe, and it can still cause serious illness, particularly in older adults and people with chronic conditions or weakened immune systems. Vaccination reduces that risk and can also lower the chance of longer-lasting symptoms.
Who & When
Recommendations are refreshed each season, so the guiding idea is to stay up to date with the current updated vaccine based on your age and health. The benefit is greatest for adults 65 and older, people with underlying conditions, those who are immunocompromised, and during pregnancy. Because guidance changes, we’ll check the latest recommendation for your situation.
The bottom line: stay up to date with the current updated COVID-19 vaccine, especially if you’re at higher risk.
Is It Safe?
COVID-19 vaccines have been given billions of times and are continuously monitored for safety. Common effects are a sore arm, tiredness, headache, or a day of feeling off as your immune system responds. Serious reactions are rare. It’s recommended in pregnancy, which also helps protect the baby.
Common Questions
Do I still need it if I’ve had COVID?
Yes, staying up to date is still recommended, since immunity from infection varies and wanes, and the updated vaccine targets current strains.
How often will I need it?
For most people it’s becoming a yearly update, similar to the flu shot, though some higher-risk people may be advised to get it more often.
